well i just heard from a t/o friend of mine that theres going to be a major fleet change for the IRT.
Half of the R142A fleet on the (6) based out of Westchester yard are going to the Kawasaki plant in Yonkers to be converted into R188's for the (7) based out of Corona Yard.
The Sets Of New Tech that is going to the (7) line will be replaced with R62's that will go to the (6). looks like 62's is coming back to the bronx.
rumor is also spreading of various 62 sets heading back to the (4)
finally the surplus of R142A's from the (6) will head to the (2) line. being based from 239th st yard A.K.A wakefield yard. making the (2) and (5) lines fully new tech train lines even though they are already full of new tech.
also the (7) line is rumored to get CBTC control signals when the final 142A's are converted.
CBTC is also rumored to be placed on the (2) and (5) lines when the surplus arrives.
sources are: 180th st, unionport yard masters, Tamara from teamspeak and bebo. looks like this is going to be the first overhaul of the 142A fleet.
